一、進口多級鼓風機產品概述
美國尼科NICO進口多級鼓風機是由電動機帶動風機葉輪旋轉,使葉片之間的氣體在離心力的作用下甩出,外界氣體通過葉輪中間形成的負壓吸入,達到連續(xù)鼓風的目的。在常規(guī)轉速下單級離心升壓有限,采用多級串接的方式可達到升壓要求,稱為多級離心風機。進口多極鼓風機可用于輸送空氣、煤氣、化工氣體爐冶煉、礦山浮選、污水處理、造氣鼓風等領域,具有噪聲低、振動小、效率高、運行平穩(wěn),安裝、維護保養(yǎng)方便,露天環(huán)境下使用等特點。常用于高爐鼓風,電廠及煉油廠脫硫鼓風,選煤跳汰機配套,高爐、焦爐煤氣、加壓輸送,及污水處理的鼓風曝氣,化工氣體的回收、加壓輸送等。在同行業(yè)中我廠產品具有用戶選型范圍廣,配套齊全的特點。
